Abstract
The utility model discloses a surely careless device of combine, including the main shaft, be equipped with a plurality of knife rests on the main shaft, be equipped with the blade in one side the same with the main shaft rotation direction on the knife rest, the blade is fixed on the knife rest through the tighten the bolts who wears to establish on the knife rest. Compared with the prior art, the utility model, the blade of blade rust can convenient and fast ground not be changed alone to main epaxial blade after using a period blade rust to save the cost of changing, maintaining.
Description
Technical field
This utility model relates to united reaper, particularly to the hay cutter on united reaper.
Background technology
Along with social development, mechanization of agriculture is more and more universal, when the crop harvesting such as Semen Tritici aestivi, Oryza sativa L., substantially carries out combine operation.In order to improve the utilization rate of wheat rice straw, it is to avoid the fire hazard brought because of crop straw burning, by configuring straw millstone on united reaper, the straw of output from united reaper is pulverized, then sheds in the middle of farmland, it is achieved straw-returning.Existing straw millstone is to arrange shredding mechanism in one end of sheller unit, is transported at shredding mechanism, shed in farmland after shredding shredding mechanism by the straw after threshing by helical feed.Chinese utility model patent such as Application No. 200920167556.4, disclose one " straw chopping of united reaper and scattering mechanism ", including rotating shaft, cut grass-removing wheel, ledger-plate, guiding shell, ledger-plate is fixed on the lower shoe guiding shell, cutting grass-removing wheel and be provided with cutterhead, cutterhead is provided with cutting blade.The passive blade of straw and ledger-plate after threshing shred, and are then spilled over guiding shell.
This technology is the most extensively used, but the typically rectangular steel plates of the cutting blade in currently available technology grinds and forms, its cutting edge because of time rust after, change very inconvenient.
Utility model content
In order to overcome drawbacks described above, this utility model provides a kind of united reaper hay cutter, and on its hay cutter, the blade for crushing straw is convenient for changing.
This utility model is achieved through the following technical solutions:
United reaper hay cutter, including main shaft, main shaft is provided with some knife rests, and described knife rest is provided with blade in the side identical with main axis direction, and described blade is fixed on knife rest by tighting a bolt of being located on knife rest.
Knife rest upper end is the intermediate plate that two panels folds against, and blade is embedded the side at two panels intermediate plate.
The centrage of the knife back distance intermediate plate of described blade has gap, is distributed two or more along centerline direction and tights a bolt in the middle part of intermediate plate, and the diameter tighted a bolt is less than the distance between the knife back and the centrage of intermediate plate of blade.
The beneficial effects of the utility model:
Compared with prior art, the blade on main shaft, after using a period of time cutting edge rust, can be individually replaced the blade of cutting edge rust, thus save replacing, the cost of maintenance this utility model conveniently and efficiently.

Fig. 2 is this utility model cutter frame structure schematic diagram.
Fig. 3 is A-A directional profile schematic diagram in Fig. 2.
Detailed description of the invention
In conjunction with Fig. 1 to Fig. 3, this utility model includes that main shaft 1, main shaft 1 are provided with some knife rests 2, and described knife rest 2 is provided with blade 3 in the side identical with main shaft 1 rotation direction, and described blade 34 is fixed on knife rest 2 by tighting a bolt of being located on knife rest 2.
Knife rest 2 upper end is the intermediate plate 5 that two panels folds against, and blade 3 is embedded the side at two panels intermediate plate 5.
The centrage of the knife back distance intermediate plate 5 of described blade 3 has gap, is distributed two or more along centerline direction and tights a bolt 4 in the middle part of intermediate plate 5, tight a bolt 4 diameter less than the distance between the knife back and the centrage of intermediate plate 5 of blade 3.
Blade 3 in the present embodiment, can directly use blade of carving knife on the market, it can also be the blade that grinds of steel disc, it is fixed on the most non-fixed form being only limitted to the present embodiment of mode of knife rest 2, can arrange through hole on blade, tights a bolt 4 through the through hole on blade, thus it is fixing, but the firmness that this mode is when reality is applied is suitable with the frame mode firmness of the present embodiment, adds this operation of punching on the contrary, causes cost increase.Can also be not provided with intermediate plate on knife rest, blade is only fixed on the side of knife rest, but so, blade itself is exposed outside, is easily broken off.
